• A) The electric field is zero at x = 0, its magnitude is at a maximum at x = 5 cm, and the field is directed to the right there.
• B) The electric field is zero at x = 5 cm, its magnitude is at a maximum at x = 0, and the field is directed to the right there.
• C) The electric field is zero at x = 0, its magnitude is at a maximum at x = 15 cm, and the field is directed to the left there.
• D) The electric field is zero at x = 10 cm, its magnitude is at a maximum at x = 5 cm, and the field is directed to the left there.

Definitions:

Terracing

The practice of shaping steep terrain to provide flat areas suitable for agriculture or ranching, or to protect soil from erosion.

Erosion

The transportation of sediment, soil, rocks, and other materials by the actions of wind, water, or ice, often leading to the reshaping of landforms.

Angle of Repose

The steepest angle at which a sloping surface formed of a particular loose material is stable.

Slope Failure

The sudden or gradual collapse of a slope that is too steep for its material to resist the pull of gravity.
